A risky situation – conflict in Ukraine and Ukraine’s nuclear reactors

Ukraine crisis raises risk for nuclear reactors, DW 10 June 14,  Ukraine’s volatility exacerbates the risk for the country’s 15 Soviet-style nuclear reactors, warn German experts. They demand more attention for the country where the world’s worst nuclear accident took place The recent news of a water shortage due to a broken pipeline affecting thousands in
strife ravaged Eastern Ukraine spells trouble for the safety of the country’s nuclear power plants.

That’s because the security and reliability of a country’s critical infrastructure like its electrical power and water grid is essential to safely run nuclear reactors.

“Once you have decided to operate a nuclear power plant or like in this case a nuclear reactor park, you must guarantee you don’t have unstable social situations and you definitely can’t have a war,” Michael Sailer, chairman of the German Nuclear Waste Management Commission and member of the German Reactor Safety Commission, told DW.

Potential for human error   “We are talking about nuclear power plants that have a high risk even when they are constructed well and properly maintained,” Sailer who also heads Freiburg-based environmental think tank Öko-Institut added. “And in the Ukraine we are talking about the additional problem that there is an increased potential for human error due to less motivated nuclear operators than elsewhere and the fact that the security features of these reactors are a lot weaker than those of modern reactors.”

Ukraine currently has four nuclear power plants with 15 reactors online providing roughly half of the country’s energy needs which makes it practically impossible to shut them down during the crisis. All of the reactors stem from the Soviet era, went on the grid in the 1980s and are similar to the Chernobyl reactor that blew in 1986 causing the worst nuclear accident in history. Ukraine’s largest plant in Zaporizhia is located about 200 kilometers from Donetsk, the epicenter of the clash between pro-Russian militants and the Kyiv government.

Danger of sabotage But it’s not just the maintenance of the technical infrastructure and the motivation of the engineers operating the reactors that has the experts worried. The continued fighting between government and pro-Russian forces including the seizure of buildings raises the risk that the country’s nuclear plants could also be drawn into the mix…….

More attention The Chernobyl ruin serves as a reminder of the danger of nuclear energy

That the command structures particularly in the east of the country are already tenuous and embattled is evidenced by the ongoing fighting, the hostage taking of OSCE observers and the seizures of public buildings. And that this can easily affect critical infrastructure is highlighted by the recent news of a broken water pipeline in Eastern Ukraine.

That’s why – notwithstanding NATO’s assistance – not enough attention is being paid to the security of nuclear power plants in Ukraine, argue the experts.

“It’s really a problem, because only very few people think about this,” said Sailer. Nuclear experts usually don’t focus on such instable situations and the people who are concerned with instable situations like diplomats usually don’t realize how sensitive a nuclear power plant is.”http://www.dw.de/ukraine-crisis-raises-risk-for-nuclear-reactors/a-17694776
